Tinea capitis in adults: A 18-year retrospective, single-centre study in Korea.
Mycoses 2019; 62(7):609-616M

Abstract

BACKGROUND

Tinea capitis (TC) is a dermatophyte infection involving hair and scalp and occurs primarily in prepubertal children. However, data on adults are limited.

OBJECTIVES

The aim of this study was to evaluate epidemiological, clinical and mycological characteristics of TC in adults in Korea.

PATIENTS/METHODS

We retrospectively evaluated 82 adults (44.3%) among 185 TC patients at a tertiary hospital during June 2000-2017.

RESULTS

Mean patient age was 66.9 ± 15.8 (20-90) years with female predominance; mean disease duration until mycological diagnosis, 22.5 (1-144) weeks; and misdiagnosis rate, 65.9%. Most common presumptive initial diagnoses were seborrhoeic dermatitis (24.4%) and bacterial folliculitis (18.3%). Chronic systemic illness and accompanying alopecia were found in 61 (74.4%) and 46 (56.1%) patients, respectively. Pustular type was found in 26.8% patients, followed by seborrhoeic dermatitis-like 25.6%, grey patch 23.2%, kerion celsi 22.0% and black dot 2.4%. Forty-eight patients (58.5%) had tinea infection at other skin areas. Microsporum canis (56.5%) and Trichophyton rubrum (21.7%) were the most common causative organisms; 92.7% patients achieved complete resolution, and seven patients (9.2%) had a recurrence.

CONCLUSIONS

We report the largest, most recent series of case studies of adult TC. Adult TC is not an uncommon problem, especially in elderly women, and has distinctive epidemiological and clinicomycological characteristics compared to those in prepubertal children. Recognising adult TC profile will help clinicians avoid misdiagnosis and provide appropriate treatment.
